Abstract

Die vorliegende Erfindung betrifft einen Freilauf (4) mit einem Innenring (38), einem Außenring (40) und mindestens einem Klemmelement (48) zwischen dem Innenring (38) und dem Außenring (40), das von einer Klemmposition, in der das Klemmelement (48) eine Drehung des Außenrings (40) relativ zu dem Innenring (38) in einer ersten Umfangsrichtung (24) verhindert, in eine Löseposition bewegbar ist, in der der Außenring (40) in einer entgegengesetzten zweiten Umfangsrichtung (26) relativ zu dem Innenring (38) drehbar ist, wobei das Klemmelement (48) mittels eines Federelements (64) in die Klemmposition vorgespannt ist. Das Federelement (64) weist einen langgestreckten Federkörper (66) auf, der in einer Radialebene verläuft und einen in radialer Richtung (20, 22) wellenartigen Verlauf aufweist. Die vorliegende Erfindung betrifft ferner eine Freilaufanordnung (2) mit einem solchen Freilauf (4).

The present invention relates to a freewheel (4) having an inner ring (38), an outer ring (40) and at least one clamping element (48) between the inner ring (38) and the outer ring (40) from a clamping position in which the clamping element (48) prevents rotation of the outer ring (40) relative to the inner ring (38) in a first circumferential direction (24), to a release position in which the outer ring (40) is in an opposite second circumferential direction (26) relative to Inner ring (38) is rotatable, wherein the clamping element (48) is biased by a spring element (64) in the clamping position. The spring element (64) has an elongated spring body (66) which extends in a radial plane and has a wave-like course in the radial direction (20, 22). The present invention further relates to a freewheel assembly (2) with such a freewheel (4).
